Colorpipe Register Description (continued)
Current zoom window width. After automatic zoom (R175:1), copy R171:1 to the snapshot X Zoom register
R166:1 (context A) or R160:1 (context B) so the snapshot has the same field of view as preview. Also copy to
snapshot X Size register R167:1 (context A) or R161 (context B) for largest snapshot.
0x0IE0
Current vertical zoom.
IR Y Shift.
0: No IR
1: 2x
2: 4x
3: 8x
Current zoom window height. After automatic zoom (R175:1), copy R172:1 to the snapshot Y Zoom register
R169:1 (context A) or R163:1 (context B) so the snapshot has the same field of view as preview. Also copy to
snapshot X Size register R170:1 (context A) or R164 (context B) for largest snapshot.
0x0C09
Zoom step sizes. Should be a multiple of the aspect ratio 5:4 for VGA or 4:3 VGA or 11:9 for CIF.
Zoom step size in X.
Zoom step size in Y.
0x0000
Resize Interpolation and zoom control.
Reserved.
S tarts automatic “zoom out” in step sizes defined in R174:1.
S tarts automatic “zoom in” in step sizes defined in R174:1.
Reserved.
0x0000
Defines sensor and colorpipe context for current frame. Registers R200:0, R200:1, and R200:2 are shadows of
each other. See description in R200:2. It is recommended that all updates to R200:n are handled by means of
a WRITE to R200:2.
See R200:2[15:0].
0x7000
This register specifies which of several special effects to apply to each pixel passing through the pixel pipe.
Solarization threshold.
S pecification of the effects mode.
“000”
“001”
“010”
“011”
“100”
“101”
0xB023
This register specifies the chroma values for the sepia effect. In sepia mode, the chroma values of each pixel
are set to this value. By default, this register contains a brownish color, but it can be set to an arbitrary color.
Sign of Cb.
Magnitude of Cb in 0.7 fixed point.

No effect (pixels pass through unchanged).
Monochrome (chromas set to 0).
Sepia (chromas set to the value in the effects sepia register).
Negative (all color channels inverted).
Solarize (luma conditionally inverted).
Solarize2 (luma conditionally inverted, chromas inverted when luma inverted).
